Seabed

The seabed (also known as the seafloor, sea floor, or ocean floor) is the bottom of the ocean.

Seabed structure

Most of the oceans have a common structure, created by common physical phenomena, mainly from tectonic movement, and sediment from various sources. The structure of the oceans, starting with the continents, begins usually with a continental shelf, continues to the continental slope – which is a steep descent into the ocean, until reaching the abyssal plain – a topographic plain, the beginning of the seabed, and its main area. The border between the continental slope and the abyssal plain usually has a more gradual descent, and is called the continental rise, which is caused by sediment cascading down the continental slope.

The mid-ocean ridge, as its name implies, is a mountainous rise through the middle of all the oceans, between the continents. Typically a rift runs along the edge of this ridge. Along tectonic plate edges there are typically oceanic trenches – deep valleys, created by the mantle circulation movement from the mid-ocean mountain ridge to the oceanic trench.

The mistakes I've madeThat caused painI could have done withoutAll my selfish thoughtAll my prideThe things I hideYou have forgot aboutThey're all behind youThey'll never find youThey're on the ocean floorYour sins are forgottenThey're on the bottomOf the ocean floorMy misdeedsAll my greedAll the things that haunt me nowThey're not a pretty sight to seeBut they're wiped awayBy a mighty, mighty waveA mighty, mighty waveYour sins are erasedAnd they are no moreThey're out on the ocean floorTake them awayTo return no moreTake them away
